Profit and Inequalities in Charity

The video tutorial concludes with word problems, focusing on a charity selling daffodils to raise money. It explains how to set up and solve an inequality to determine the minimum number of daffodils needed to make a profit. The tutorial emphasizes understanding the problem, setting up variables, and applying inequality knowledge. The solution shows that selling more than 50 daffodils ensures a profit, and if the charity has 55 daffodils, they can achieve this goal. The lesson highlights the importance of extracting information and applying mathematical concepts.

What is the main goal of the charity in the word problem?

• To donate daffodils

• To reduce costs

• To buy more daffodils

• To sell daffodils for a profit

How much did the charity spend on supplies?

• $750

• $500

• $250

• $100

What is the selling price of each daffodil?

• $5

• $3

• $2

• $4

What is the potential revenue from selling one daffodil?

• $6

• $5

• $4

• $3

What is the cost of supplies in the word problem?

• $100

• $200

• $300

• $250

What variable is used to represent the number of daffodils sold?

• F

• E

• D

• C

What inequality represents the condition for a positive profit?

• 5D ≤ 250

• 5D > 250

• 5D = 250

• 5D < 250

What is the main challenge in solving the word problem?

• Calculating the cost

• Setting up the inequality

• Finding the selling price

• Buying the daffodils

How many daffodils must be sold to achieve a positive profit?

• At least 52

• At least 53

• At least 50

• At least 51

Why is the inequality considered strict?

• Because daffodils are expensive

• Because you can't sell half a daffodil

• Because the charity needs more money

• Because the cost is too high
